Key Performance Advantages
- All raw materials including steel coils, welding wires, and fluxes undergo strict physical and chemical inspections to ensure product quality from the source.
- Pre-forming processes include leveling, trimming, planing, surface cleaning, and pre-bending treatment to ensure plate quality and high-precision forming.
- Electric contact pressure gauge controls conveyor pressure for smooth strip steel transportation.
- Advanced external or internal control roll forming technology.
- Weld seam gap control device ensures pipe diameter, alignment, and gap meet welding standards.
- Internal and external welding performed with American Lincoln electric welding machines using single/double wire submerged arc welding for stable, reliable quality.
- Air plasma cutting machine provides accurate, smooth cuts on steel pipes.
- Comprehensive final inspection system includes weld mechanical properties, chemical composition, fusion condition, surface quality, and non-destructive testing.
X-ray Steel Pipe Inspection
Continuous ultrasonic testing marks on weld seams undergo manual ultrasonic and X-ray inspection. Any defects are repaired and retested until cleared. Strip steel butt welds, spiral weld intersections, and T-joints are inspected by X-ray television or film.
Fully Automatic Steel Pipe Hydrostatic Testing Machine
The hydraulic testing machine is mainly used for pressure testing of welded pipes, and has the functions of computer recording, storage, printing, and test results. It has the advantages of high efficiency, high testing pressure, and strong safety. The pipe diameter range is from Φ 20 to Φ 3500mm, and the test pressure is 10-110MPa.
Fully Automatic Flat Head Chamfering Machine
The flat head chamfering machine is mainly used for flattening and chamfering the ends of welded pipes. Equipped with a contour chamfering knife, the processed groove is uniform and beautiful. Our company provides flat head chamfering machine processing range for steel pipe production enterprises, covering steel pipe diameters ranging from 20mm to 3500mm, while meeting standards such as API-5L, API-5CT, BS1387-85, ASTM, GB9711, etc.
